Fisheries Report No 16 - Notes On The Wildlife Of A Proposed Nature Reserve Around Lake Grace And Lake Chinokup, Western Australia, N. L. Mckenzie, W. K. Youngson

Fisheries Research Reports

During 1972 and 1973 plants and vertebrate animals were collected and recorded from a proposed 22 000 ha nature reserve centred on a chain of salt lakes in south-western Western Australia (33° 10' S - 33° 35' 8 and 118° 19' B - 118° 29' E).

The dominant plant species were collected, the structural formations desert bed and a vegetation map produced. Seven species of native terrestrial mammal and three species of bat were recorded.

Three of the terrestrial species are endemic to southwestern Western Australia, and two of these - Pseudomys occidentalis and Sminthopsis granulipes - are regarded as …

Decide : How Much Superphosphate, G A. Robertson, J. W. Bowden, N. J. Halse

Journal of the Department of Agriculture, Western Australia, Series 4

* A 400 per cent increase in ihe price of superphosphate has reduced the economic optimum rates of super for crops and pastures in 1975.

* Many factors, both biological and economic, must be taken into account in determining the rate of superphosphate to apply.

• DECIDE, a model developed by CSIRO and the Department of Agriculture, provides a formal system in which all these factors can be considered.

• DECIDE is based on the results of all research on superphosphate carried out in Western Australia. However, each farmer's own knowledge of his farm, the soils, crops and animals is …

The Doublegee Problem In Western Australia, D J. Gilbey

Journal of the Department of Agriculture, Western Australia, Series 4

Doublegee is native to South Africa and is now naturalised as a serious weed of crops and pastures throughout the temperate areas of Australia.

Doublegee was introduced for cultivation as a vegetable by English migrants to the Swan River Colony in 1830, and a bed of doublegees is known to have been sown at Mr. J. Phillips' property on the Canning River in 1833. However, the plant soon became a troublesome weed and its name was changed from Cape spinach to Tanner's curse and later to doublegee.

More than 180 doublegee seedlings per square metre have been counted in a …

Peanuts For The Ord, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Peanuts were extensively tested in experiments on the Ord River in the early 1950s, but it is only recently that varieties better adapted to heavier soils have re-opened prospects of commercial production.

The new varieties remain dormant after maturity and an irrigation just before harvesting allows the crop to be lifted with the soil friable enough to reduce harvesting losses and the amount of soil sticking to the kernels.

These varieties have been extensively tested in Department of Agriculture trials at Kimberley Research Station since 1958, and preliminary recommendations for crop production and pest and disease control have been formulated.

Lupinosis, M R. Gardiner

Journal of the Department of Agriculture, Western Australia, Series 4

In spite of many years of intensive investigation lupinosis remains a remarkably complex and baffling problem. Current research is throwing new light on the disease and it is now much better understood— although far from beaten.

Lupinosis research is co-ordinated by the Department of Agriculture's Lupinosis Committee, on which are represented all groups working on the disease. These include veterinary surgeons and pathologists, chemists, plant pathologists and animal husbandry specialists.

Chairman of the Committee is Dr M. R. Gardiner, Chief of the Department's Animal Division and a veteran of lupinosis research.

In this article Dr Gardiner summarises the current state …

Docks In Western Australia, J M. Allen

Journal of the Department of Agriculture, Western Australia, Series 4

A survey carried out by the Department of Agriculture has shown that docks are the most serious weed of the higher rainfall areas of Western Australia. They are estimated to cost farmers $400 000 annually in lost production. One of the main reasons why they are important weeds is that they regenerate rapidly from tubers and compete with desirable annual pasture species. Also the upright dock flowering stems are woody and unpalatable. Individual plants become intertwined and deter stock from grazing summer pastures.

Results from the survey of the dock problem are given in this article. The findings show that …

Fungicides And Insecticides For Control Of Rose Pests, Paul F. Webb

Masters Theses

The author was requested by a representative of the Ortho Chemical Company to test various fungicides and insecticides on hybrid tea roses.

Roses are one of the most time consuming and most difficult ornamentals to manage due to several diseases and insects that attack them. Two of the first and foremost skills that the author had to acquire were the proper planting and the subsequent care of roses.

The purpose of the research project was to compare the effectiveness of experimental products with presently available fungicides and insecticides. Before new chemicals can be marketed much data must be collected to …

Midsummer Standing Crops Of Wetland Sedge Meadows Along A Transect From Forest To Prairie, Eville Gorham, John M. Bernard

Journal of the Minnesota Academy of Science

Midsummer standing crops of wetland sedges have been measured along a transect from forest to prairie in northwestern Minnesota. The eight forest stands, all but one on waterlogged fibrous peats, are dominated by Carex lacustris (4 stands), C. lasiocarpa (2), C. rostrata (1) and C. atherodes (1). They exhibit above-ground standing crops ranging from 425 to 738 g dry wt/m2, with a mean of 606 g/m2. The five prairie stands on well-drained silty peats are all dominated by Carex atherodes, and their standing crops range from 679 to 1248 g dry wt/m2, with a mean of 941 g/m2. Above-ground standing …

Castanea Pumila Var. Ozarkensis (Ashe) Tucker, Comb. Nov, Gary E. Tucker

Journal of the Arkansas Academy of Science

Castanea ozarkensis Ashe, the Ozark chinquapin of the vascular plant family Fagaceae, is distributed widely throughout the Interior Highlands of Arkansas and the adjacent states of Missouri and Oklahoma. Examination of material from throughout the range of C. ozarkensis indicates demonstrable morphological intergradation with C. pumila (L.) Miller sensu lato, the chinquapin of wide distribution in much of the eastern United States. It is proposed that C. ozarkensis be reduced to C. pumila var. ozarkensis (Ashe) Tucker, comb. nov.

Germination Ecology Of Three Chihuahuan Desert Crucifers, Larry L. Bell

Dissertations and Theses @ UNI

Seeds of Lepidium lasiocarpum Nutt., Lepidium medium Greene var. medium, and Descurainea pinnata (Walt.) Britton ssp. ochroleuca (Woot.) Detling, native to the Chihuahuan Desert, were tested for their germination responses under conditions of constant and fluctuating temperatures, light and dark sensitivity, and different seed depths in soil. The effects of a three day drying period alternating with one day of moisture at field capacity was also investigated. All three species germinated optimally under fluctuating temperatures with low temperatures near 5-10°c and high temperatures near 20-25°C. L. lasiocarpum seeds responded better to fluctuating temperatures of 15°c magnitude than to fluctuations of …
